(...) Not to put too fine a point on it, but RUN, PRGM and VIEW are read from an I/O port, while the ON/OFF button is tied to an interrupt line. That's what lets you wake the RCX up from a deep sleep, which you can't do with the other buttons. Ralph (20 years ago, 9-Feb-05, to lugnet.robotics.rcx)

(...) BrickOS does allow you to configure how the buttons are used. The RUN and Power buttons are read in the BrickOS "firmware", so you'd need to change the kernal, if you want to do other things with them, but it is very possible. So, yes, the run (...)

Hi Everybody, I have used SendSpybotMsg and SendSpybotCtrlMessage (of course in connection with resopective set messages) without any problems using BCC 3.3.7.5 and 3.3.7.9. These two commands gives RCX a nice control over spybot. Specially (...) (20 years ago, 8-Feb-05, to lugnet.robotics.spybotics, lugnet.robotics, lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)
